Answer:
A(w) = w(3w-2)
A(2) = 8 . . . . square feet
Step-by-step explanation:
For width w, the length will be 3w-2, two feet less than 3 times the width. The area is the product of length and width, so is ...
A = WL
A(w) = w(3w-2)
__
To find the area for a width of 2, we put 2 where w is, then evaluate.
A(2) = 2(3·2 -2) = 8 . . . . square feet
Answer:
m = dv
Step-by-step explanation:

What you just do is multiply <em>v</em> on both sides so <em>m</em> can be isolated.
Answer:
37/60
Step-by-step explanation:
Number of spaces would be number of squares - 1
You would have 12 squares and 11 spaces.
Multiply number of each by their size then add the two together:
12 x 7 1/4 = 87 inches
11 x 3 5/16 = 36 7/16 inches
Total = 87 + 36 7/16 = 123 7/16 inches
Answer: 123 7/16 inches
